摘　　要：本文旨在明确不同剂量的苹果蠹蛾Cydia pomonella性信息素主成分E8,E10-12:OH对梨小食心虫性信息素的增效作用,为梨小食心虫的监测及生物防治提供参考。通过田间诱捕试验和触角电位技术,探究了不同剂量的E8,E10-12:OH和梨小食心虫性信息素混配对梨小食心虫雄虫田间诱集效果及触角电位反应的影响。田间试验结果表明,5种剂量E8,E10-12:OH均对梨小食心虫有引诱活性,但各剂量间诱集效果差异不显著;5种剂量E8,E10-12:OH与梨小食心虫性信息素混配处理的田间诱集效果均显著高于对照(梨小食心虫性信息素),其中20μg E8,E10-12:OH与梨小食心虫性信息素混配的诱捕量是对照的2.86倍;梨小食心虫雄虫对E8,E10-12:OH和梨小食心虫性信息素的触角电位反应均随剂量增大而增强。E8,E10-12:OH可作为梨小食心虫引诱剂或性信息素的增效剂,提升对梨小食心虫的诱捕效果,精准其种群发生动态监测。The aim of this paper was to clarify the synergistic effect of different doses of E8,E10-12:OH that is the main component of sex pheromone of Cydia pomonella on the sex pheromone of Grapholita molesta,and to provide a reference for biological control and monitoring of G.molesta.Field trapping experiments and electroantennogram(EAG)were used to explore the effect of lures,which contained different dosages of E8,E10-12:OH mixing with the sex pheromone of G.molesta,on trapping efficiency of G.molesta in the field and on the EAG responses of male G.molesta.Field experiment showed that all five doses of E8,E10-12:OH used alone had a capability to trap male G.molesta and had no significant difference in trapping number of male G.molesta.Trapping efficiency of five doses of E8,E10-12:OH mixing with G.molesta sex pheromone were higher than it.The number of G.molesta captured by adding 20μg of E8,E10-12:OH to the sex pheromone of G.molesta was 2.86 times higher than it.Both E8,E10-12:OH and G.molesta sex pheromone could elicit the EAG responses of male G.molesta,of which the intensity was positively related with the concentration of tested compounds.E8,E10-12:OH could be used as attractant or synergist of the sex pheromone of G.molesta to improve its trapping efficiency and enhance the accuracy of monitoring the population dynamics of G.molesta.
